Digital Preservation in Finland

Ministry of Education and Culture
13th Meeting of the Member States Expert Group on
Digitisation and Digital Preservation
Digital preservation of cultural heritage –
why? Because we have to
• the National Archives Service, the National Library, the National
Audiovisual Institution, the National Board of Antiquities, the
National Gallery, and numerous other Finnish institutions are
obliged to preserve digital information for future users.
• Legislation concerning the generation, use, dissemination,
utilisation and preservation of digital cultural heritage include:
–
–
–
–
–
–
the Finnish Archives Act
the Act on Collecting and Preserving Cultural Materials
the Museums Act
the National Board of Antiquities Act
the Act on the Finnish National Gallery
the Copyright Act
The challenge
Digital preservation refers to the reliable preservation of digital
information for several decades or even centuries.
→ Hardware, software, and file formats will become outdated, while the
information must be preserved.
Digital preservation is not just a technical challenge.
→ It also requires operational, cognitive, financial, legal, and skills
capabilities to be managed successfully.
Could the memory institutions just do it by
themselves?
• The information systems used by organizations responsible for the
preservation of digital cultural heritage materials do not have the
functionalities required for digital preservation (such as integrity
monitoring, refreshment, and migrations).
• Organizations also lack data management processes focusing on
digital long-term preservation.
Digital preservation: what is needed?
• a suitable information system: steady stream of
changes in technical systems and components
from the start.
• interorganizational cooperation, system
interoperability and compatibility of digital
information
Digital Preservation in NDL
•
The Digital preservation (DP) is a system of
services which is offered for partner organisations:
–
–
•
These organisations will transfer the materials
intended for long-term preservation to the NDL’s
DP service
•
•
•
•
•
under the administration of the Ministry of Education
and Culture
preserving cultural heritage
preparing and packaging materials is the most visible part of the
preservation for the partner organizations - specifications and
guidelines need to be maintained to make this happen
The ownership of materials will remain with the
organisations which stored them.
Bit level preservation started 2014
The aim is to have full functionality of the DP
system in use by 2016
Current capacity of the DP system is 0,5 PB
which is stored on 3 different media types
(disk and two tapes)
• Contents knowledge and semantics
• Descriptive metadata
Semantic preservation
• Preservation planning
DP Solution
Partner organizations
Preserving digital objects requires expertise
on different preservation layers
• Administrative & technical metadata
• File formats
• Preservation actions
Logical preservation
• Materials & replication management
• Storage media
• Storage device
Bit-level preservation
Long-term
utilization
Standard Portfolio
• Catalogue of common standards used by services and interfaces
of National Digital Library
• Enables provision of consistent services, combining data, and
developing metadata
– Semantic commensurable
• Early adoption of Standard Portfolio enabled archives, libraries
and museums to be ready for enhancements in data
interoperability
• This portfolio constitutes a key part of the National standard
portfolio (a recommended set of standards for all public
organisations in Finland)
National Digital Library of Finland
The Ministry of Education and Culture launched the National Digital
Library (NDL) in 2008.
The objective the National Digital Library is to make the digital
cultural heritage of archives, libraries and museums available to the
public now and in the future.
The project promotes interoperability of processes and IT systems in
Finnish memory organizations
The NDL project includes:
– Common user interface Finna for the information resources
of libraries, archives and museums.
– Digitisation of the most essential cultural heritage materials
of libraries, archives and museums.
– Development of a digital preservation solution for digital
cultural heritage.
– National Digital Library works as an aggregator for the
European Digital Library Europeana.
